Yes, lvm1 used 25 and a fresh lvm2 install uses 26, but switching from
lvm1 to lvm2 leaves the start script at 25. This causes a severe bug for
those running lvm on raid, since mdadm also starts at 25, but after the
old lvm25 (by alphabetical ordering).
For example, on my system I run three raid one components: md0 (which
becomes /boot), md1 (which becomes /) and md2 which becomes an lvm. But,
because lvm gets ahead of mdadm, the md2 raid device does not get
started properly, only using one of the disks, with the other one
somehow rendered inoperable.
